| Abstract/Contents: | "Seventeen Kentucky bluegrass, Poa pratensis, cultivars were evaluated for sensitivity to ozone (O3) and sulfur dioxide (SO2) by exposure on tow dates to either 40 parts per hundred million (pphm) O3 or 20 pphm SO2 for 2 hours at 26 °C, 92% relative humidity, and an illumination of 21,520 lux. Cultivars differed significantly in sesitivity to both phytotoxicants. The range in sensitivity among cultivars was not as great for SO2 as for O3. Cultivar response differences to both O3 and SO2 injury were sufficiently consistent to indicate genetic differences within this species. Several cultivars had practical levels of resistance. A differntial response among cultivars was generally obtained with the two pollutants." |
